TM5402 media 'shuttle' control

button, your viewing will jump to the point shown on the timeline.
The longer you hold the button for, the faster the timeline progresses. For the first 5 seconds, it seems to progress at around 2x, the next 5 seconds are approx 4x, then next 5 seconds approx 8x, then it flies through, untill you release the button.
Big thanks to digidude for working this out]]>
